Purpose : To evaluate the prevalence of refractive errors in children of rural zone of Londrina City, Brazil.

Methods : A retrospective, cross-sectional study was performed evaluating the medical records of children who participated of Projeto Primeiros Olhares (“First Sight Program”) conducted by HOFTALON - Hospital de Olhos - Londrina “Londrina Eye Hospital”, during 2017. Children from 01 through 12 years of age were evaluated according to gender, uncorrected visual acuity, refractive error and treatment.

Results : 500 eyes were evaluated. The average age was 6,2 years-old; 51,8% were male and 48,2% female. Decreased uncorrected visual acuity (VA <0,7) was observed in 10% of children. Refractive errors occurred in 15%. The spherical equivalent demonstrated Hyperopia (>+1,5D) in 10% and myopia (<-0,5D) in 2%. Astigmatism (<-0,5D) occurred in 12%. High ametropias as high myopia (< -3,00D) was observed in 0,6%, high hyperopia (> 3,00D) in 1% and high astigmatism (< -3,00D) in 0,6%. Optical corrections were prescribed for 90% of children with refractive error.

Conclusions : Refractive errors occurred in 15% of the evaluated children. Astigmatism and Hyperopia were the most frequent refractive errors observed.
